Washington DC: UK’s Lord Christopher Monckton, a former science advisor to Prime Minister Margaret Thatcher, claimed House Democrats have refused to allow him to appear alongside former Vice President Al Gore at high profile global warming hearing on Friday at 10am. Monckton told ClimateDepot.com that the Democrats rescinded his scheduled joint appearance at the House Energy and Commerce hearing on Friday. Monckton said he was informed that he would not be allowed to testify alongside Gore when his plane landed from England Thursday afternoon.

“The House Democrats’ don’t want Gore humiliated, so they slammed the door of the Capitol in my face,” Monckton told Climate Depot in an exclusive interview. “They are cowards.”

According to Monckton, Rep. Joe Barton (R-Texas), Ranking Member on the Energy & Commerce Committee, had invited Lord Monckton to go head to head with Gore and testify at the hearing on Capitol Hill Friday. But Monckton now says that when his airplane from London landed in the U.S. he was informed that the former Vice-President had “chickened out” and there would be no joint appearance. Gore is scheduled to testify on Friday to the Subcommittee on Energy and the Environment’s fourth and final day of hearings on the American Clean Energy and Security Act of 2009. The hearing will be held in 2123 Rayburn House Office Building.

According to Monckton, House Democrats told the Republican committee staff earlier this week that they would be putting forward an unnamed ‘celebrity’ as their star witness Friday at a multi-panel climate hearing examining the House global warming bill. The ‘celebrity’ witness turned out to be Gore. Monckton said the GOP replied they would respond to the Democrats ‘celebrity’ with an unnamed ‘celebrity’ of their own. But Monckton claims that when the Democrats were told who the GOP witness would be, they refused to allow him to testify alongside Gore.

“The Democrats have a lot to learn about the right of free speech under the US Constitution. Congress Henry Waxman’s (D-CA) refusal to expose Al Gore’s sci-fi comedy-horror testimony to proper, independent scrutiny by the House minority reeks of naked fear,” Monckton said from the airport Thursday evening.

“Waxman knows there has been no ‘global warming’ for at least a decade. Waxman knows there has been seven and a half years’ global cooling. Waxman knows that, in the words of the UK High Court judge who condemned Gore’s mawkish movie as materially, seriously, serially inaccurate, ‘the Armageddon scenario that he depicts is not based on any scientific view,’” Monckton explained.

A call to the Democratic office of the House Energy and Commerce Committee seeking comment was not immediately returned Thursday night.
